What people say
The smaller back fin loosens up the tail of your board, and the CI template overall is credited with dependable drive and effortless release.
Hexcore is 25% lighter than normal solid fiberglass fins, without compromising performance.
Run the small Hexcore set on a shortboard if you're a lighter surfer or mostly surf smaller, weaker waves and want a loose, responsive tail that turns quick. If you're heavier or surf powerful waves and need more hold, the large set is the call — this one would feel free where you want locked-in drive.
More About This Fin
The CI Tri Small is a three-fin thruster set designed with the Channel Islands team and foiled by True Ames, based on the template Chuck Ames developed across decades of foiling thruster sets for Channel Islands. This version is the small size in Hexcore construction with FCS-compatible tabs; Hexcore displaces glass and resin with hexagonal coremat, running about 25% lighter than solid fiberglass with slightly softer flex. A Futures-compatible version of the same small Hexcore set is also made.
